Infrastructure and Industrial Contractors
Water and Wastewater Construction Estimating
Tribuild supports water and wastewater contractors with multi-discipline quantity takeoffs: process concrete structures, process piping and equipment, and mechanical, electrical, and I&C scope, built from the drawings for treatment-plant and pump-station bids.
Treatment-plant bids are multi-discipline by nature: process concrete, piping, equipment, mechanical, electrical, and I&C on one job. Tribuild quantifies each process area: cast-in-place structures by volume with reinforcing and waterstop, process piping by material and service, and equipment counted by tag.
Mechanical, electrical, I&C, and sitework are carried for the disciplines approved for delivery, and every deliverable ships with documented assumptions (including the field and existing-plant risk that stays with the contractor) your team can price and defend.
What we estimate for water and wastewater contractors

Process piping
Process and yard piping by size, material, and linear foot.
Process equipment
Clarifiers, blowers, screens, and process equipment counted by tag.
Tanks and basins
Cast-in-place and package tanks/basins by volume and unit.
Concrete structures
Process concrete (walls, slabs, channels) by volume with reinforcing and waterstop.
Underground utilities

Project experience
How it works
- 1
You submit drawings, specifications, addenda, and bid information, and book your call in the same step.
- 2
The project is assigned to the appropriate estimator or team, and questions and clarifications are documented where necessary.
- 3
The deliverable is reviewed under Tribuild's applicable quality-control process and delivered before your call.
- 4
On the call we review the completed deliverable together and capture the formats and process your team needs.
- 5
You choose how you engage us: per project, hourly, per square foot, per dedicated estimator, or a monthly or annual SLA.
- 6
You are set up on the Tribuild portal with a dedicated point of contact and a POC email address for day-to-day communication.
- 7
Scope changes and preferences are recorded continuously in your Scope of Work, which stays live in the portal, and revisions and addenda are managed under the applicable service agreement.
Quality control
- Quantities reconciled against process, structural, and civil drawings
- Concrete carried by structure with waterstop and reinforcing
- Process piping separated by material and service
- Equipment counted against the equipment list
- Addendum tracking against plant revisions

Frequently asked questions
Process, structural, mechanical, electrical, and I&C drawings, the equipment list, P&IDs, civil/yard plans, and specifications. These support a multi-discipline takeoff.
We quantify the disciplines approved for delivery on the engagement (process concrete, piping, equipment, mechanical, electrical, I&C, and sitework) and state which are included.
By structure and volume with reinforcing and waterstop carried, since water-holding structures have detailing that drives cost.
Means and methods, final pricing, and licensed engineering remain with the contractor and design team.
Yes, always. Color-coded PDFs and Excel workbooks are standard, and the native source files are included with every deliverable.
